Model numbers and document revisions: which specification belongs where
An EU declaration of conformity identifies the product by serial number, model or type and states its issue date, according to Your Europe. These fields answer different questions: which product the declaration covers and when it was issued. A later document date alone does not identify a different hardware model. [1]
KEY TAKEAWAYS
Product identity and changes to a declaration
Your Europe lists product traceability, the manufacturer, relevant legislation, signature and issue date among the declaration’s fields. It says the declaration must be reviewed and updated for changes to the product, applicable legislation, manufacturer details or assessment procedures. AMCA likewise places model and size on a fan graph. Product identity remains part of the evidence even when the document is revised. [1][2]
What to record about a document revision
Our reading: For editorial records, keep the document title, publisher, version label and visible date together. If a revision date is absent, record it as unknown. The day a reader downloaded a document establishes access, not when the manufacturer changed its contents.
Checking whether a revised document applies
Our reading: compare the product identifier in the document with the identifier on the equipment, then preserve the version label and visible issue date. If the issuer does not state that a revised document covers the older model, leave that applicability unresolved. The paired guide shows how to record these fields without treating the date of access as a manufacturer revision date.

Commercial resource from our ecosystem
The project owner states that BELOM A2 has completed laboratory testing and that documentation for the applicable EU CE-marking requirements is prepared. NailWiki has not examined the reports or conformity declaration. We therefore publish no A2 filter class, airflow, noise value or capture percentage. A CE mark is not an independent dust-capture rating.
